I purchased a ChiliPad™ for my hospital bed several months ago. I am very happy with it. Being a big person I found that equal temperature through out the mattress pad is great. It has helped me with the heat generated from my air pressure mattress with the latex encasement which doesn’t allow the heat from the air tubes to escape, the ChiliPad™ does defuse the heat from my body therefore lessening to a big degree the skin irritation i had been experiencing since I got the air pressure mattress almost 2 years ago. KEEP UP THE GOOD WORK.
